A natural acidic glassy volcanic lava non-metallic mineral, including perlite, turpentine, and obsidian, with only different crystal water contents. Due toUnder high temperature conditions of 1000-1300 ℃, its volume rapidly expands by 4-30 times, hence it is collectively referred to as expanded perlite. Generally, the expansion ratio is required to be greater than 7-10 times (obsidian>3 times, usable), and the silica content should be around 70%. All are open-pit mining. No need for ore dressing, just crushing and sieving.
main purpose
Can be used as a carrier for filters, catalysts, molecular sieves, and rubber. Widely used in sectors such as construction, metallurgy, petroleum, machinery, light industry, hydropower, casting, food, agriculture, forestry, and horticulture. Constant thermal conductivity0.0245～0.048W/(m·K)， High temperature thermal conductivity coefficient of 0.058-0.175W/(m · K), low temperature thermal conductivity coefficient of 0.028-0.038W/(m · K), operating temperature of 800 ℃. Used as insulation and cold insulation filling material. Soilless cultivation, soil improvement, water and fertilizer retention in agriculture and horticulture.
Expanded perlite is a widely used inorganic mineral material, involving almost all fields. For example:
① Used as filling insulation material in oxygen concentrators and cold storage.
② Used for filtering products such as alcohol, oil, food, and wastewater.
③ Used as fillers and expanders for rubber, paint, coatings, plastics, and other materials.
④ Used as a sensitizer.
⑤ Used for adsorbing floating oil.
⑥ Used for agriculture, horticulture, soil improvement, water and fertilizer retention.
⑦ Used to mix with various adhesives to produce profiles of various specifications and properties.
⑧ More widely used for thermal insulation of industrial kilns, building roofs, and walls.
Note: In addition to the thermal insulation properties of expanded perlite, the application of various expanded perlite products is based on this, and different binders can be added to make products that meet different needs.
Our company is located 25 kilometers southwest of Langfang City, in the central area of the Beijing Tianjin metropolitan area of the Bohai Rim Economic Zone. It is 70 kilometers away from Beijing, 60 kilometers away from Tianjin, and 120 kilometers away from Tanggu Port in Tianjin. It is adjacent to five * * highways, including 104 and 106, with convenient transportation, forming a unique advantage for developing our factory's economy based on the central city and seaport. It is currently a diversified processing plant for perlite series products in Hebei region. Since our establishment, we have been committed to the research and development of perlite series products. Expanded building perlite meets the needs of the construction market in surrounding cities such as Tianjin, Beijing, Langfang, and Baoding. In 1996, we developed hydrophobic perlite insulation boards. Entering the field of chemical engineering. In 1999, we developed and produced perlite filter aid as a filtering material for food, chemical, and industrial applications. In 2002, it produced horticultural flower perlite, which is exported to Japan, South Korea, Türkiye and other Middle East countries. Production of low-temperature insulation material - pearl sand began in 2003. Simultaneously developed hydrophobic bead gloss sand. This product overcomes the disadvantage of water absorption of pearl sand, and the air moisture content is close to the standard. We have proficiently mastered a set of operating procedures and techniques for producing perlite series products. Our factory produces air separation equipment, including deep cold insulation materials (SCP-50), (SCPP-60), and pearl sand (SCP-150) heavy materials. The 150 type heavy material is mainly used for insulation of the cold box foundation of air separation equipment. Our products have excellent quality and reasonable prices, and are used in large and small air separation equipment, becoming a good insulation material for air separation equipment. The technical indicators meet the strict requirements of high-tech equipment at home and abroad. This product has been tested by the Institute of Refrigeration and Cryogenics at Zhejiang University, and all indicators meet the technical requirements. Our company has an annual production capacity of over 100000 cubic meters of perlite and strong technical strength. This product is made by high-temperature puffing, with stable performance and reliable quality. All employees of our factory are willing to offer high-quality products and a good corporate reputation. We sincerely welcome domestic and foreign customers to come and negotiate business. We hope that our cooperation can become friends of * * and that common development is our common goal.
